These are my 1966 O-Pee-Chee Batman cards. Black Bat, Red Bat and Blue Bat. All three sets are complete. These are the OPC Canadian version. They're identical to the American version except it states Printed in Canada. They're significantly more rarer than the U.S. cards and represent less than 1% of the entire market share. Trying to find high grade cards in this series is extremely difficult.
